Pitchbook

See: Venture Capital. See: A Round Financing. See: Angel Investor.

The pitchbook is the book in which your pitch (or ask for money) is contained.

Slideshare.com has oodles of examples of these puppies. Basically, a pitchbook for an early stage venture startup explains how the usually-very-complex technology works, what the market for it is, how big it is, how the company does something very hard that people want, how much money it'll take to get version 1.0 of its product out there, who's gonna run the show, etc. That's a pitchbook for funding for a seed or early stage venture round.

But pitchbooks are used at the other end of the spectrum as well. Goldman Sachs is hired to raise $200 billion for Greece because, well, you know, the country has no idea how to manage its own money. So even the vaunted GS puts together a pitchbook (young MBAs' core grid of work), so that Greece looks like it has turned the corner; all the bad is behind it, and now, all of a sudden, its unions will have a clue. Its wealthy will stop absconding with taxable wealth. Its government will be somewhat less corrupt. Woot.

Different number of zeros after the dollar sign (or euro or whatever). but same idea. You're pitching for money from investors.
